2,802,491 Patented Aug. 13, 1957 2 I the main valve 2 is associated witha piston 9 as de scribed in that application.

The by-pass 11 leads to two injectors 12a and 12b and to two pressureintakes 13aand 13b which are located at different levels'in the tank tobe filled. The intakes 13a and 13b are connected to the cylinder9b atdifferent heights by the conduits 15a. and 15b.

Finally, a cock 5 controls a by-pass 1c of the conduit 1 supplying theliquid, as described in the parent application; j

The operation of this device is as follows:

'In orderto fill the tank, the cock 5 is opened and the pressure liquid,by acting on the face 9d, lifts the piston 9 and the valve 2. Theopening of the said valve 2 en-. ables the liquid to penetrate into thetank and into the conduit 11. The jets 12a and 12b send forth streams ofsubstantially cylindrical shape, the cross-section of which issubstantially equal to the cross-section of the orifices of the jets 12aand 12b and which streams strikethe pressure intakes 13a and in thepreceding examples.

The pressures produced in the intakes 13a and 13b are transmitted viathe conduit 15a and 15b to the chamber 9e. The cock 5 is now closed. Theintakes 13a and 13b maintain within the chamber 9e a pressure whichsuffices to keep the valve 2 open despite the thrust exerted on thepiston by the liquid coming from the conduit 1. When the liquid levelreaches the ejector 12b, the pressure of the intake 13b falls and theliquid within the chamber 9e is urged through the conduit 15b which actsas an escape and causes the pressure to .fall :in the chamber 9e., Thevalve 2 closes until the piston .9'blocks the conduitlSb and the flowtherefore continues. at reduced speed until the ejector 12a is in itsturn immersed in the liquid. Atthis moment the pressure of the intake 13a falls, the liquid inthe chamber 9e is evacuated through the conduit15a, and the valve 2 is completely closed;

It should be pointed out that the by-pass 1c and th cock 5 might beeliminated, a spring being then provided in the chamber 9e, to urge thevalve towards its open position. The mere force of the said spring isalone insuflicient to prevent the closure of the valve 2 when the flowvof liquid through the conduit 1 is normal. On the other hand, the forceof this spring alone is sufiicient to open the valve 2 when the pressureof the fluid in that part of the main conduit 1 which is situatedup-stream of the main valve 2 falls. .In this case, at the moment whenthis part of the main conduit 1.is subjected to pressure, the valve 2 isopened and the pressure intakes 13a and 13b come into action immediatelycreating pressure in the chamber 9e .which, with the aid of the saidspring, suffices to keep the valve 2 open. When the action of the saidintakes 13a and 13b ceases, the force of the said spring, which is nowthe only force, is insufficient to oppose the closing of the valve2under the effect of the liquid pressure for a normal flow. The valve 2thus closes automatically and'only reopens when the pressure has droppedsufficiently. This arrangement also enables the receptacle to be emptiedthrough the filling orifice.

In most of the examples described in the parent application, the jet 12and the tube 13 are arranged in an enclosed chamber 11c. The existenceof the said chamber, although recommended, is not necessary,particularly in the case in which the jet 12 and the tube 13 are liableto be flooded by the liquid located within the receptacle which is to befilled, as shown in Figure 6 of the parent application.

The device shown in Figure 2 differs from that shown in Figure 5 of saidapplication Serial No. 319,985 more particularly by the followingpoints:

(a) The end of the chamber 11c which accommodates the member 13 is openinstead of closed;

gb) .The press-button 5 of Figure 5 is replaced by a,

member a controlled by a lever 5 similar to the lever of the nozzlesshown in Figures 1 to 4 of the parent application; v "-(c)The shaft 7 isrigidly secured to the valve 20;

(d) The conduit 9 which is closed as 'in Figure'S by the two auxiliaryvalves 20 and 20a, is also closed in certain positions up-stream of thesaid va lves 20land 20a by a third auxiliary valve 20b which issubjected to the action of a spring; 7 V

(e) A ball 24a is located in a cavity 24 which opens into the chamber11c and is so inclined that in the positions corresponding to normal useof the nozzle the ball 24 remains in the cavity 24a and emergestherefrom in all other positions;

(f) A plug 25a consisting of a readily fusible material seals a conduit25 which-connects the chamber 90 to the exterior; V

The operation of this latter type of nozzle is as follows:

In order to fill a tank, the end of the hose-cock is inserted into thesaid'tank until the orifice 17 islocated at the stop level which is tocause the cessation of the filling. After the operator'has set-thesupply .pump in operation, he presses on the lever 5 against the spring16. This has as'its immediate effect the removal ofthe valve from itsseating. The valve 20a then opens, despite the action of the spring 10,because of the pressure prevailing in that part of the conduit 1 whichis situated up-stream of the valve 2, the valve 20b remaining off itsseat. Under these conditions, the up-stream pressure is transmitted tothe face 9d of the piston. Under. the influence of the various pressuresacting on the assembly consisting of the valve 2 and the piston 9, thevalve '2 opens until the valve 20 isoVertaken' by the shoulder of theconduit 9 said shoulder forming the seat of the valve 20. The conduit 9]is then. againclosed. Two cases may occur:

First case.The flow through the by-pass 11 is insuflicien-t toensure inthe intake 13 a pressure whichis of itself sutficient to keep the valve2 open. In this case, as soon as the conduit 91 is closed, the valve 2tends to be closed until it reaches a position slightly less open thanthe position corresponding to closing of the conduit 9 by the valve 20.Thus it is possible to regulate as desired the quantity of the flow bydisplacing the lever 5 more or less, but it must be pointed out that theclosing of the hose-cock is no longer automatic and depends on the willof the operator.

Second case.The flow in the by-pass 11 is suflicient to ensure apressure in the intake 13 suflicient to maintain the valve 2 open. Inthis case, the liquid flows away through the slot 11a in the by-pass 11and emerges from the jet 12 in the form of a stream which strikes thepressure intake 13 as in the case of Figure 5 of said application SerialNo. 319,985. As described with referenceto that figure, the valve 2 alsotends to a large opening but is prevented therefrom in this case by thevalve 20 which forms a stop. The instant at which the valve 20 serves asa stop depends on the state of compression of the spring 16, whichdepends on the wish of the operator. Thus the latter can, by means ofthe lever 5, regulate the extent to which the spring 16 is compressedand so regulate the degree of opening of the valve 2.- When the openingof the latter is sufliciently large, the valve 20b closes the inletup-stream of the-conduit 9 this latter action not causing anyinconvenience since the pressure of the intake 13 on the face 9d issuflicient to maintain the valve 2 in its open position. When the liquidin the tank reaches the orifice 17, the air no longer arrives by theconduit 19 and the orifice 18. The stream of liquid issuing from thenozzle 12 fans out immediately after egress from the said nozzle andloses speed. The pressure drops and possibly disappears altogether-inthe intake 13. The pressure on the face 9d therefore falls. Theresultant pressure acting on the valve 2 and piston 9 is then such thatthe valve 2 closes. Closure of the valve 2 then shuts the by-pass 11 butduring this displacement, the valve 20b, the cross-section of which islarger than that of the inlet of the conduit 9 stays forced on its seatby the liquid pressure on its up -stream side, despite the return actionof the spring 4b, which neutralises the effect of the opening'of thesaid conduit 9 by the valve consequence of the descending movement ofthe piston 9, the lever 5 still being supposed to be held in one of itsopening positions. After the closure of the valve 'Z'du'e to thepressure drop in the intake 13, if' the operator completely releases thelever 5, the pressures on the two faces of the valve 2% are equalised asa result of the presence of a slot forming by-pass in the disc of saidvalve and the valve 2% is dislodged by the action of the spring 4b. Theapparatus can then function again.

If the operator does not. release the lever, the valve 20 remains openand impedes the balance between the pressures on the two faces ofthevalve20b. The .la'tte'r thus remains seated and preventsifurtherflowr pIf, bymistake, theoperator dropsthe hos'e-cock-while it is pouring, thesaid hose-cock;cannot be :kept balanced in a normal jpouring position,since the ball 24a. emerges from its cavity 24- byits own v weight andlocates itself in the trajectory of the stream issuing from themember-12, whence there results a disturbance in the chamberll'c andpremature closing of the valve 2.

.If a fire breaks out inthe vicinity. of the hose-cock the temperaturerises and ends by melting the plug 25a, so that the pressure in thechamber 9 is relieved through the conduit 25 and the flow stops. I Iclaim: V I
